View Full Version : [ubuntu] Wireless Network With File Server - Security Question
September 21st, 2008, 05:29 AM
Im pretty new to Linux but in the near future I'm going to be getting a server from a friend of mine with Ubuntu Linux on it. Once I get it I intend on installing Samba on it so I can use it as a network drive for my 2 other PC's(Windows).
They are both wireless and are used wireless constantly(move around alot) and I was wondering how secure it would be to have a wireless file server.
Right now via my router I have a few security settings:
-Anti-Spoof(Defends against spoofed IP and MAC addresses)
With the Ethernet cord running directly into the server and setting it in my router that only the local ip's of my 2 computers can access the server should that be enough security to protect my files on the server from being viewed by an intruder?
Thanks in advanced.
edit: Also if someone could explain what the eth0 eth1 etc system is that would be cool. If not I'll figure it out.

That sounds pretty secure to me. You can also set up restrictions on who can access the server through Samba.
As far as explaining the "eth0 eth1 etc. system", that's kinda a broad question. Basically, each network interface on the system gets labeled ethx, where x is replaced with the number of the network interface, starting at 0. For example, if you had three network interfaces, you would have eth0, eth1, and eth2. If that doesn't make sense, isn't clear, or doesn't answer your question, feel free to PM me.

I made a little diagram of what I want to do--is it possible?

If you think you're network is going to be actively attacked then you need to make sure you have a solid WPA password. It's the only way to make sure your data is safe, also, by the way, Mac Address filtering, and Hiding the SSID provide no extra security.

That diagram looks fine; that's pretty much what my network looks like.

It's the only way to make sure your data is safe, also, by the way, Mac Address filtering, and Hiding the SSID provide no extra security.Thanks for telling me that. I knew that SSID's could be easily found even with broad cast off, just not all wireless devices can find it. I also know that Mac Addresses can easily be spoofed. There is some thing on my router thats called Anti-Spoof protection. I read that it's mainly for spoofed IP filtering, and I don't know how reliable it is.
So that leaves me with the WPA encryption. Should I use WPA or WPA2. From what I have read WPA is more secure but WPA2 is more compatible. Right now I have it set to mixed but all my devices are using the WPA anyway so should I just change it to WPA?
And thanks again Virtual

I think you may have it backwards on WPA/WPA2 WPA2 is newer, and isn't supported on as many devices. From the small amount of research I just did via google, I'm getting the impression the WPA2 is more secure, but WPA is still very secure as long as you use a strong passphrase.

Okay so I got my server and got everything running the way I want to... for the most part.
I installed Webmin and started to configure Samba. I configured it to how I thought it should be configured I guess I messed up somewhere.
I keep getting this error when I try to create a new folder on the server in Windows: "You need permission to perform that action" Did I mess something up?
